Actually there are many ways to tell if you have a bad cat.

.A rotten egg smell coming out of the exaust

.Hesitation and/or bucketing when acceleration takes places

.Increase in engine running temp

.A ratteling in the muffler as car idles

.Car dying sparatically due to engine backpressure

.Difference in temperature from the back of the converter to the front due to clogging

There's no possible way to pass inspection with a bad catalytic converter, if if you find out you have a bad catalytic converter during your inspection you have a chance after you after you have replaced the catalytic converter and the inspection no no charge/free!!

No, the catalytic converter is downstream from the EGR valve so it has no effect on it.

Transmission torque converter or an exhuast catalytic converter?

A bad coil can damage a converter. If the engine is misfiring, it will cause raw fuel to get into the converter and that can cause failure.

A bad catalytic converter can cause hard starts if it has become clogged. This produces excessive back pressure in the engine.
